Wireless Terminal, Wireless Base Station, and Transmission Method of Buffer Status Report

2. The wireless terminal according to claim 1, wherein the buffer size corresponds to a size of the uplink data stored in memory.

3. The wireless terminal according to claim 1, wherein the memory includes a buffer for storing the uplink data.

4. The wireless terminal according to claim 1, wherein the buffer size corresponds to a size of the uplink data stored in buffer.

5. The wireless terminal according to claim 1, wherein the controller selects index from a plurality of indices without the second index.

6. The wireless terminal according to claim 1, wherein the memory stores the buffer status table in which a range from a minimum value of the buffer to a maximum value of the buffer is divided into a plurality of subranges, the plurality of subranges being associated with a part of the plurality of indices.

7. The wireless terminal according to claim 1, wherein the controller transmits the buffer status report at predetermined period.

9. The wireless terminal according to claim 8, wherein the buffer status report includes a field which stores the index, the field being defined with a length of 8 bits.

12. The wireless terminal according to claim 11, wherein the another buffer status table is assigned to a logical channel group used in a transmission service having large transmission capacity, and the buffer status table is assigned to another logical channel group used in another transmission service having transmission capacity smaller than that of the transmission service.
